Hi,
The standby nodes maintain a copy of the primary node. In the event of a failure or maintenance. The standby node is immediately promoted to primary and begins serving requests while a replacement standby node is provisioned in the background; so there won’t be any downtime.

I hope this helps!

Hello,
As there is a standby node, I believe that there should be minimal to no downtime during the upgrade.
